BACKGROUND

Internet Protocol (IP) cameras connect to a network and transmit data using networking protocols. Many IP cameras are designed to be placed on a surface (e.g., a desktop) and as such include a flat base (which comes into contact with the desktop or other surface) which supports the camera. IP cameras so constructed cannot be easily mounted to different locations or surfaces (e.g., to a wall where drilling a hole is not possible or permitted) or used in different conditions (e.g., indoor/outdoor, night/day, mobile/stationary, etc.). New cameras and/or camera accessories which overcome some or all of these shortcomings would be desirable.

Unless stated otherwise, a component such as a processor or a memory described as being configured to perform a task may be implemented as a general component that is temporarily configured to perform the task at a given time or a specific component that is manufactured to perform the task. As used herein, the term ‘processor’ refers to one or more devices, circuits, and/or processing cores configured to process data, such as computer program instructions.

A detailed description of one or more embodiments of the invention is provided below along with accompanying figures that illustrate the principles of the invention. The invention is described in connection with such embodiments, but the invention is not limited to any embodiment. The scope of the invention is limited only by the claims and the invention encompasses numerous alternatives, modifications and equivalents. Numerous specific details are set forth in the following description in order to provide a thorough understanding of the invention. These details are provided for the purpose of example and the invention may be practiced according to the claims without some or all of these specific details. For the purpose of clarity, technical material that is known in the technical fields related to the invention has not been described in detail so that the invention is not unnecessarily obscured.

Various embodiments of housings for a video camera are described herein. Oftentimes video cameras (especially high definition (HD) video cameras) are relatively expensive (e.g., as high as $500) and a user may not want to buy multiple cameras for different purposes. In some embodiments, a user purchases multiple housings (e.g., priced on the order of $30 or less) and uses the same camera with a selected one of the housings when a certain utility or application is desired (e.g., depending upon the location to be captured by the camera or the nature of the video recording). In some cases, a housing is semi-permanently installed or mounted in a location. For example, a user may use a camera as a security camera when the user is away on vacation or traveling for work. An outdoor housing may be kept installed or mounted near a front door or other entrance to the home, even though the user may not always use the camera as a security monitor and/or the camera may not always be in the outdoor housing. This may make it easier when the camera is used for that purpose since the camera will be pointing in the desired direction and the user does not have to re-mount the outdoor housing each time.

The housings described herein are exemplary and are not intended to be limiting. For example, any dimensions, shapes, styles, and/or materials described herein are exemplary and are not intended to be limiting. Drawings are not to scale. For brevity, features or characters described in association with one embodiment may not necessarily be repeated or reiterated when describing another embodiment. Even though it may not be explicitly described therein, a feature or characteristic described in association with one embodiment may be used by another embodiment.

FIG. 1 is a diagram showing an embodiment of a housing which includes an arm, joint, and base. In the example shown, camera 100 is a camera which is configured to be housed in or otherwise coupled to a variety of enclosures or housings, for example, at least temporarily until it is removed from a first housing and (if desired) placed in another housing. In some embodiments, module camera 100 is used as-is, without any housing.

Housing 102 and wall mount 104 show embodiments of a housing and mounting hardware, respectively. Housing 102 includes arm 106, joint 108, and base 110. Housing 102 is one example of a camera holder which includes a (in this case, circular) cutout configured to hold or otherwise support the video camera and/or point the video camera in a desired direction. To mount the camera on a wall, screws are drilled through the mounting screw holes to attach wall mount 104 to a wall in the desired location. Then, housing 102 is “popped” into wall mount 104. The proper angle for video recording by camera 100 is achieved by rotating the housing within mount 104 and/or by pivoting housing 102 forwards or backwards (e.g., bending at joint 108). In various embodiments, camera 100 is inserted into housing 102 before housing 102 is coupled with mount 104, or afterwards as desired.

Compared to some other cameras, camera 100 when used with housing 102 and mount 104 may have a much lower profile, so that it is closer to the wall than some other cameras. Also, installation may be much easier using housing 102 and mount 104. Some other cameras may require screws to be installed alone (e.g., without any guide or mount as shown here) and then the camera is positioned so that the screw heads fit into openings in the housing of the camera, mounting the camera to the wall. One problem with this is that it may be difficult to insert the screw heads into the opening and get the camera to mount to the wall snugly (e.g., because the user cannot see inside the camera). In contrast, the example system shown herein permits housing 102 to rotate within mount 104.

In this embodiment, camera 100 includes a Wi-Fi antenna and includes a Wi-Fi transceiver (not shown) for communicating in a Wi-Fi network. In some embodiments, a user is able to view video captured by camera 100 remotely and/or via a network, for example from an Internet browser application (e.g., Microsoft's Internet Explorer or Mozilla Firefox) running on a computer, from a dedicated and/or downloaded application running on a smart phone, etc. Camera 100 includes a status light, indicating when the device is powered on and/or filming. For example, one color light may indicate the device is powered on but not recording and another color light may indicate filming; no light may indicate the device is powered off Camera 100 further includes an HD (e.g., 720p, 1080p, or higher) camera, microphone, and 12 infrared (IR) light emitting diodes (LEDs). (Exemplary configurations or features described in association with this figure (such as the pixel resolution of camera 100 or the number of LEDs) are exemplary and are not intended to be limiting.) If light is low, camera 100 is configured to use the IR LEDs to operate in a nighttime mode. In this particular example, the IR LEDs are not visible from the exterior since they are enclosed with a dark-colored, IR-transparent plastic. Since the plastic permits infrared light to pass through it, the camera can function when the lighting is poor and the IR LEDs are used. Camera 100 further includes a speaker (e.g., so a person viewing video from the camera can talk to someone being filmed by the camera). Camera 100 includes a Universal Serial Bus port (i.e., female adapter) to which a USB plug (i.e., male adapter) is able to be coupled in order to supply power and (during an installation mode) is used as an input/output interface via which information about the Wi-Fi network is supplied to camera 100 (e.g., name of the Wi-Fi network to become a member of, an encryption key, etc.). In various embodiments, a USB connector is a Type A, Type B, Mini-A, Mini-B, Micro-A, or Micro-B connector. The USB port may be used at other times and/or for other purposes. For example, batteries or solar power generators with USB connections may be used to power the device and make it portable. The USB port may also be used as an I/O interface for control or display. In some embodiments, video captured by camera 100 is stored and may be accessed and manipulated (e.g., copied to another storage devices, etc.) as desired.

FIG. 2 shows a front view and a side view of an embodiment of a camera inserted in a housing. In the example shown, camera 100 and housing 102 from FIG. 1 are shown. Camera 100 combined with housing 102 (and optionally further combined with mount 104, not shown) may be used in a variety of applications. In some embodiments, camera 100 is used as a baby camera, for example to monitor an already-sleeping child or to confirm that a child has gone to sleep. Camera 100 may be free standing (e.g., on a dresser) or may be mounted on a wall using mount 104. Other example uses include monitoring unsupervised nannies or maids, monitoring latchkey children before parents come home from work, video conferencing, pet cameras, as a store security camera to deter shoplifting or record evidence, etc.

Although the embodiments described herein show a circular camera and circular cutouts, in some embodiments, a camera may be some other shape. In such embodiments, the housings which are configured to house the camera correspondingly have different cut-outs or couplings for the camera.

In some cases, it may be desirable to use a camera outdoors and a housing is designed to withstand the elements and/or for outdoor mounting. The following figures show some embodiments of an outdoor housing for a camera.

FIG. 3 is a diagram showing an embodiment of an outdoor housing for a camera with an AC power plug. In the example shown, views 300 a-300 c show an outdoor housing for a camera from first, second, and third side views, respectively. As shown in view 300 a, the housing includes AC power plug 302, power adapter and battery 304, and mini-USB plug 306 Electrically, power is received from AC power plug 302 which is used to charge a battery within power adapter and battery 304. AC power plug 302 and power adapter and battery 304 are two examples of a power supply which is electrically coupled to a video camera.

In the event there is a power outage (or, for whatever reason, AC power plug 302 no longer supplies power), camera 308 will be able to operate for at least some additional time with the power stored in power adapter and battery 304. Power is supplied to camera 308 from power adapter and battery 304 via USB plug 306. As described above, the configurations and features described in association with this figure are merely exemplary and are not intended to be limiting. For example, although this exemplary camera system has a USB connection, other embodiments use other types of connections to exchange power (e.g., Power over Ethernet (POE)) and/or to exchange data (e.g., Ethernet).

Mechanically, camera 308 is coupled to the housing in view 300 a by inserting camera 308 into an opening of the housing so that USB plug 306 is inserted into the USB port (not shown) of camera 308. USB plug 306 is one example of a connector in a housing which is configured to be physically coupled to a camera. In this particular example, USB plug 306 is not designed to be pulled out of the housing in view 300 a and the housing of view 300 a has a cutout matching the shape of camera 308 to aid in insertion of camera 308. In some other embodiments, there is some slack in a wire connecting a USB plug to a power adapter and battery; this permits a USB plug to be pulled out of a housing (e.g., for improved visibility and easy insertion). Connection occurs by pulling out a USB plug, inserting the plug into a camera (while being able to view and align the USB plug and port), and then inserting the coupled USB plug and camera into the opening of the outdoor housing. To attach or connect the system to a wall or other surface, AC power plug 302 is inserted into an AC power outlet. AC power plug 302 is one example of a surface mount which is configured to (at least temporarily) connect the system to a wall or other surface.

Since outdoor power outlets are located at various heights above ground, USB plug 306 is adjustable and the outdoor housing in view 300 a has a slanted surface, permitting camera 308 to be angled forward or backward. If the housing in view 300 a is coupled to an outdoor power outlet which is relatively high above ground (e.g., close to a roofline), then camera 308 may be angled forward using adjustable USB plug 306 in order to monitor things below. Conversely, camera 308 may be angled backwards if an outdoor power outlet is located relatively low to the ground. In various embodiments, a housing may be configured to permit a variety of adjustments in a variety of directions or axes (e.g., horizontally from left to right).

Although view 300 a shows AC power plug 302 as being side mounted, in some other embodiments, some other orientation or placement is used (e.g., a top mounted or a side mounted AC power plug).

View 300 b shows a second side view of the example housing, looking at it from the side that includes AC power plug 302. View 300 c shows a third side view of the example housing, looking at it from the side that includes camera 308. For clarity, camera 308 is shaded.

FIG. 4 is a diagram showing an embodiment of an outdoor housing for a camera with light bulb connectors. In the example shown, housing 400 includes light bulb outlet plug 402, power adapter and battery 404, USB plug 406, and light bulb port 408. Housing 400 is designed to screw into a light bulb outlet, such as a porch light or other outdoor lighting fixture, using light bulb outlet plug 402. Since many outdoor light outlets are designed to have a light bulb oriented upwards, light bulb outlet plug 402 is on the bottom of housing 400. Alternatively, a light bulb outlet plug may be on some other surface (e.g., side or top mounted). Light bulb outlet plug 402 is another example of a surface mount which (at least temporarily) connects the system to a lighting fixture (or, more generally, a surface).

Electrically, power goes from light bulb outlet plug 402 to power adapter and battery 404. As in the housing embodiments described above, the battery in power adapter and battery 404 permits a camera to operate even if power from light bulb outlet plug 402 is lost. Power adapter and battery 404 powers both USB plug 406 and light bulb port 408. Light bulb 414 is coupled to and powered by light bulb port 408. This permits a camera to be powered using an outdoor lighting fixture (such as a porch light), without depriving the area of light.

Camera 410 is coupled to housing 400 via USB plug 406. As described above, USB plug 406 and/or the wire between power adapter and battery 404 and USB plug 406 may be configured in a variety of ways to make insertion of camera 410 easier. For example, porch lights tend to be relatively high off the ground and even tall people may have difficulty inserting camera 410 into housing 400 when housing 400 is already coupled to an outdoor lighting fixture. (Housing 400 may, for example, be coupled to a lighting fixture all the time and camera 410 is only inserted when the homeowners plan to be away from home for an extended period of time.) Easy insertion and removal of camera 410 would be desirable.

In this particular example, USB plug 406 is able to be bent forward so that camera 410 can be angled forward. As described above, most outdoor lighting fixtures are relatively high off the ground and an expected configuration may be to angle camera 410 downwards. Although not shown herein, in some embodiments a housing is configured so that a camera can be angled backwards (i.e., to look up) and/or adjusted horizontally (i.e., left/right).

Dome 412 encloses light bulb 414 and is connected to housing 400. The rounded shape of dome 412 is merely exemplary and in some embodiments a variety of covers in different colors, styles, finishes, and so on are available so that people can choose the cover that suites the style of a house and/or a homeowner's taste. Similarly, housing 400 may be available in a variety of colors, styles, and finishes. Universal connectors 416 ensure that any of the housings will be able to fit any of the covers. The shape of universal connectors 416 is merely exemplary and a variety of connectors (e.g., nuts and bolts, clamps, etc.) may be used.

In some embodiments, housing 400 further includes a light sensor (not shown) which turns off the power supplied to light bulb port 408 (and thus light bulb 414) from power adapter and battery 404 when it is light outside and turns on power when it is dark outside. This (for example) permits a light switch controlling a porch light or other outdoor light fixture to always be on without wasting power to power light bulb 414 when not needed.

If left outdoors for an extended period of time, dome 412 may become dirty and affect the quality of the video captured by camera 410. In some embodiments, a monitoring process is performed, which alerts a user when the monitoring process determines a dome or other cover to be too dirty. In various embodiments, a monitoring process is performed on camera 410 or at a server to which video is uploaded (e.g., www.dropcam.com). In some embodiments, video captured by camera 410 is analyzed to detect when dome 412 is too dirty. For example, an amount of light may be measured or otherwise determined from the video. In some embodiments, if an amount of light at a fixed or predefined time of day (e.g., noon) drops below a threshold, then it is determined a cover is getting dirty. The threshold may vary based on location and/or time of year (e.g., Ohio in winter versus Florida in summer). In some embodiments, a monitoring process looks for a drop in light levels by comparing amounts of light at the same time of day and/or time of year (e.g., an amount of light at 2 PM on Aug. 1, 2012 versus an amount of light at 2 PM on Aug. 1, 2009, or an amount of light at 2 PM on August of 2012 versus an amount of light at 2 PM on August of 2009). In some embodiments, the first few minutes captured by the camera are set to be a clean image or clean level and a monitoring process measures a change between current conditions and the clean image or level. In various embodiments, an email notification is sent and/or a user is presented with a warning message when logging on to a (e.g., cloud-based) video system.

FIG. 5 is a diagram showing an embodiment of an outdoor housing with a solar panel. In the example shown, views 500 a and 500 b show the first and second side view, respectively, of an outdoor housing with a solar panel. In some embodiments, the housing shown is used where there is no outdoor AC power outlet or outdoor lighting fixture (e.g., a shed or other structure with no power supply).

As shown in view 500 a, the exemplary housing includes wall mounting hardware 502, power adapter and battery 504, USB plug 506, and solar panel 508. The position of solar panel 508 is able to be adjusted (e.g., forwards/backwards as well as pivoting on the stand) so that light exposure is maximized. Power from solar panel 508 is passed to and stored by power adapter and battery 504. From there, power is supplied to USB plug 506 for camera 510 operation.

View 500 b shows how wall mounting hardware 502 is used to mount the exemplary housing to an outdoor wall or other surface. In this example, screws are used to hold the housing of view 500 b in place. In some other embodiments, some other connectors or hardware may be used.

In some cases, it may be desirable to use a camera indoors but a flat surface is not available. Alternatively, a flat surface is available but it is undesirable to place a camera there. The following figures show some embodiments of indoor housings which may be used in such situations.

FIG. 6 is a diagram showing an embodiment of a housing with side grippers. In the example shown, view 600 a shows a front view of the exemplary housing, which includes side grippers 602 which are designed to wrap around vertical poles or bars. Some examples include attaching the exemplary housing to the side of a crib, or to the handrail of a staircase, balcony, or landing. Side grippers 602 (and in some embodiments, the entire housing) are made of flexible and/or material that grips, such as rubber. Side grippers 602 are bent backwards, wrapped around the desired poles or bars, and released. The exemplary housing and the camera are relatively light so the surface friction of side grippers 602 is sufficient to hold the housing in place.

View 600 b shows a bottom view. As shown in view 600 b, camera 612 is inserted from the back of the housing through a hole in the housing. Battery 604 is inside of the housing in view 600 b and is not visible from the exterior. Wire 608 connects battery 604 to USB plug 610, which in turn is plugged into camera 612 to supply power. View 600 b includes opening 606 where excess wire can be tucked back into the body of the housing in view 600 b. In some embodiments, the edge of 606 is elastic so that opening 606 can be stretched open when wire 608 is being inserted or removed but otherwise remains relatively closed, keeping excess wire inside the exemplary housing.

In some embodiments, battery 604 is charged using USB plug 610. In some embodiments, battery 604 is removable so that charged batteries can be swapped in for discharged batteries with minimal interruption to camera 612. In such embodiments, opening 606 may be wider to accommodate the insertion and removal of battery 604. In some embodiments, power is able to be supplied from an AC power source and/or via a power cord (e.g., in addition to or as an alternative to battery power). For example, when used as a baby monitor, it may be desirable to have an unlimited power supply without worrying about how long a battery will last.

FIG. 7 is a diagram showing an embodiment of a housing with hook and loop fasteners. In the example shown, the housing is similar to that shown in FIG. 6, in that they both are designed to be attached to vertical poles or bars, with some differences. View 700 a shows a front view of the exemplary housing. Camera 710 is top loaded into a pocket or cavity in the housing of view 700 a via opening 702. A round, front cutout in the housing permits at least part of camera 710 to be exposed on the front side of the housing. As described above, in some embodiments, the opening is elasticized. Since camera 710 is top loaded and not rear-loaded through a hole in the housing, battery 704 in this figure may be larger than battery 604 in FIG. 6. Another benefit to top loading is that the camera may be less likely to fall out of the housing.

View 700 b shows a bottom view of the exemplary housing. When coupling camera 710 to the housing, USB plug 708 is pulled out of the body of the housing (e.g., via opening 702) and is connected to the USB port (not shown) of camera 710. Once coupled, USB plug 708 and camera 710 (plus any excess wire 706) are put in the body of the housing.

Hooks 712 and loops 714 (e.g., Velcro) are used to fasten the housing to vertical bars or poles by wrapping hooks 712 around the bar or pole and attaching it to loops 714. Naturally, the positioning of hooks 712 and loops 714 may be reversed. In some cases, hooks and loops may be preferred over the side grippers shown in FIG. 6 because hooks and loops may permit a wider range of distances between the bars or poles to which a housing is attached and/or a wider range of circumferences of such bars or poles.

FIG. 8 is a diagram showing an embodiment of a housing with a clip. In the example shown, housing in views 800 a and 800 b include clip 804 which is used to attach the housing to a display (e.g., a television or a computer monitor). Naturally, housing in views 800 a and 800 b may be attached to some other surfaces or things besides televisions or computer monitors.

Electrically, power is input from AC power plug 810. The power is passed to power adapter 808. In some embodiments, power adapter 808 includes a battery (e.g., in case there is a power outage). Power is passed from power adapter 808 to USB plug 806 of the housing in view 800 a, which is connected to the USB port (not shown) of camera 850.

View 800 a shows that the example housing has no top, which may be attractive for a variety of reasons. Camera 850 is relatively light, so the coupled USB port and plug are sufficient to hold camera 850 in place even when the coupled camera 850 and the housing in view 800 a are attached to the left side or right side of the display. This design feature may make insertion/removal easier, may keep costs down, and produces a smaller and easier to store housing.

View 800 b shows a side view of the example housing. To attach the housing of view 800 b, the arms of clip 804 are pinched and the housing of view 800 b is attached to the desired surface or object. Joint 802 permits the housing of view 800 b (and camera 850, when coupled to the housing) to be angled forward or backward, so that the camera (when inserted in the housing) can be aimed at a desired object or space. View 800 b also shows plug 809, which connects AC power plug 810 to power adapter 808. In this example, the wire which includes plug 809 and AC power plug 810 may be decoupled from the housing in view 800 b for easier storage or transport. In some embodiments, a housing includes storage space for excess wire, such as a cavity with guides around which excess wire can be wrapped.

FIG. 9 is a diagram showing an embodiment of a housing which is configured to be connected to a port of a display. In the example shown, display 908 includes port 902. Wire 906 connects housing 900 and display 908. In this particular example, wire 906 may be decoupled from housing 900 and/or display 908 (e.g., for easy storage).

In various embodiments, port 902 includes a power connection (e.g., from which camera 904 can be powered by display 908) and/or a data connection (e.g., via which video data captured by camera 904 can be sent over or to a network via display 908). Some examples of port 902 include (but are not limited to) a USB port (e.g., in a computer monitor), an Ethernet port (e.g., in a television with built-in networking capabilities), or a High-Definition Multimedia Interface (HDMI) port.

As an example of a port (902) which is capable of exchanging data, a user may subscribe to both television service and cable-based Internet service from a cable company and display 908 includes a built-in cable modem (not shown) or, more generally, a transceiver. In some such configurations, video data from camera 904 is uploaded to a server (e.g., www.dropcam.com) via port 902 and the built-in cable transceiver (not shown). A user may then (e.g., at some later time) access the uploaded video data by logging on to the server (not shown). In another example, display 908 may have built-in wireless capabilities (e.g., a built-in IEEE 802.11 a/b/g/n, also referred to as WiFi, transceiver). Display 908 may (e.g., if the system is so configured) send video data from camera 904 to a local display and/or receiver, such as a computer or smart phone on the same WiFi network as display 908 and/or a computer or smart phone in the same room or house as display 908. In yet another example, video data from camera 904 may be shown (e.g., directly) on display 908. The examples above are not intended to be mutually exclusive and the system may be configured to perform any combination of the above.

In order to communicate according to the protocols and/or communications interfaces supported by port 902, housing 900 may include appropriate components (e.g., encoders/decoders, modulators/demodulators, and/or communications interfaces) as needed. For example, housing 900 may include components and/or hardware associated with HDMI, USB, and so on. In some embodiments, these components are implemented as semiconductor devices, such as an application-specific integrated circuit (ASIC) or a field-programmable gate array (FPGA).

A housing which is configured to be connected to a power and/or data port of a display may be attractive for a variety of reasons. For example, it may be unsightly to have cables or wires running from camera 904 to an AC power outlet (e.g., if display 908 is a wall-mounted television and there are no other visible wires). AC power outlets may also be at a premium and using display 908 to power camera 904 frees up an AC power outlet for another device. Although camera 904 includes wireless capabilities and can transmit video data wirelessly, it may be desirable to transmit video data over a wire line connection via display 908 (e.g., over cable-based Internet service) since a wire line connection may be less noisy and/or may have higher data transmission rates than a wireless connection.

FIG. 10 is a diagram showing an embodiment of a housing which is configured to be connected to a display using hooks and loops. In the example shown, loops 1002 are coupled to housing 1000 and hooks 1004 are coupled to display 1006. In some embodiments, an easily detachable adhesive (e.g., 3M Command™ strips) adheres loops 1002 to housing 1000 and hooks 1004 to display 1006. Loops 1002 and hooks 1004 are coupled to attach display 1006 to housing 1000 (and camera 1050, when further connected). The combined weight of camera 1050 and housing 1000 is relatively light, so hooks and loops are sufficient to hold camera 1050 and housing 1000 in place. Although this figure shows housing 1000 attached to the top of display 1006, housing 1000 and camera 1050 may be attached to a side, front, bottom, or back surface of display 1006 if desired.

In some embodiments, a housing for a camera may be (if desired) further coupled to other accessories or add-ons. The following figures show some examples of housing 102 from FIGS. 1 and 2 to which an add-on may be further coupled.

FIG. 11 is a diagram showing an embodiment of a housing and a tripod prior to being coupled together. In the example shown, camera 1100 is coupled to housing 1102; housing 1102 is similar to housing 102 shown in FIGS. 1 and 2. The bottom of housing 1102 is screwed into tripod 1104 when desired. In some embodiments, some other connector is used to couple housing 1102 and tripod 1104. Tripod 1104 may provide a more stable base than housing 1102 alone and/or permit usage of camera 1100 on an uneven surface.

FIG. 12 is a diagram showing an embodiment of a housing and a tripod after being coupled together. As shown in the front view, housing 1102 may be pivoted on tripod 1104 so that camera 1100 can be directed (e.g., to the left or right) to point in a desired direction. As shown in the side view, housing 1102 may be angled forwards or backwards, also to direct camera 1100 in a desired direction.

In some embodiments, it may be desirable to house a camera in a discreet or hidden housing. For example, a person may wish to monitor their cubicle or office to ensure that someone is not going through their possessions at night. Alternatively, a parent of a toddler (who is able to get out of bed by themselves) may wish to hide a camera so the child is not attracted to the camera and plays with it. In some cases, it may be desirable to have a multipurpose housing which performs some other task (e.g., in addition to housing a camera and/or supplying power to the camera). Multi-purpose housings may be attractive because of their ability to reduce clutter and/or if there is a limited amount of space. The following figure shows one embodiment of a housing which may be used in such scenarios.

FIG. 13 is a diagram showing an embodiment of a housing associated with a clock. In the example shown, housing 1300 includes a clock which displays the time, day of the week, and date. It is not necessary for camera 1302 to be coupled to or inserted in housing 1300 in order for the time and date features of housing 1300 to operate properly. For brevity and clarity, components (e.g., electronic components) of housing 1300 associated with displaying the exemplary time and date information are not shown in FIG. 13.

In this particular example, the housing of housing 1300 includes an opening or hole via which camera 1302 is exposed. In some embodiments, the material and/or color of the base of housing 1300 matches the material and/or color of camera 1302 so that camera 1302 is not as noticeable. In some embodiments, a housing has no hole or opening through which a camera is exposed (e.g., the base of housing 1300 is smooth and unbroken and camera 1302 resides completely within the base of housing 1300). In some embodiments, the base of housing 1300 is made of a transparent material (e.g., so that if needed, the camera is able to capture video through housing 1302).

Pet owners may wish to use their cameras to capture what their pet does throughout the day. The following figure shows an embodiment of a housing which may be used to record the indoor or outdoor activities of a pet, such as a dog or a cat.

FIG. 14 is a diagram showing an embodiment of a housing associated with a pet collar. In the example shown, housing 1400 is designed to be worn by a pet, such as a dog or a cat. Camera 1450 is coupled to housing 1400 and is exposed via a hole or opening in housing 1400. This permits camera 1450 to record what a pet is looking at or facing towards. For brevity, some details associated with a collar are not shown herein but are not necessarily excluded from the housing. For example, a variety of fasteners (not shown herein) may be used to close a collar, including buckles, hooks and loops, clips, etc.

Housing 1400 includes battery 1402, wire 1404, and USB plug 1406. In some embodiments, the material of housing 1400 is washable and battery 1402, wire 1404, USB plug 1406, and camera 1450 may be removed from housing 1400 so that it can be washed in a washing machine. For example, housing 1400 may have one or more zippers or hook and loop fasteners which, when opened, permit the removal of delicate components before cleaning. In some embodiments, this also permits battery 1402 and/or camera 1450 to be easily removed or inserted (e.g., in order to download video captured by camera 1450 or replace a depleted battery with a charged battery).
